SNAP-HOOK.

Specification of Letters Patent.

Patented Aug. so, 1918.

Application filed May 16, 1917. Serial No. 169,089.

To all whom it may concern:

Be it known that 1, JOHN B. BAXTER, citizen of the United States, residing at 'Watervliet, in the county of Albany and State of New York, have invented certain new and useful Improvements in Snap- Hooks, of which the following is a specification, reference being had therein to the accompanying drawing. a

This invention relates to improvements in hooks, and more specifically such hooks as are provided with attaching eyes at the inner ends of their shanks as suggested in my application for Letters Patent, executed of even date herewith, and specifically desig nated Case A.

The present improvements have reference to an improved type of relatively permanent closure for the eye portion of a hook, involving a special mounting and interfitting of a bar adapted to bridge the opening of the eye.

The nature of the present invention will be better understood from the specific description hereinafter contained when read in connection with the accompanying drawings forming part hereof, and wherein the preferred embodiment of the invention is illustrated.

In the drawings,

Figure 1 is a face view of a snap hook provided with the present invention.

Fig. 2 is an edge view of the same.

Fig. 3 is a sectional view; and,

Fig. 4: is a perspective view of the closure bar detached.

Referring more specifically to the drawings, wherein like reference characters designate corresponding parts in the several views, A represents the shank and B the snap hook end thereof, as known in the art.

0 represents a hook-like member formed integral with the shank and centrally disposed with reference to the longitudinal axis of the shank, said hook-like member being cast integrally with the shank to constitute without further treatment the bend or bearing end of the eye I). The end of the hooklike member terminates, as shown, in a plane parallel to the shank and at a point spaced from the shank to originally'form an opening through which the ring or chain link is adapted to be passed into the eye.

To close the opening just referred to, I provide a bar E of approximately the size of the hook-like member to a-fiord the desired strength, said bar being secured in place to constitute a permanent closure in the manner now to be defined.

At one side of the shank A in line with the free end or terminal of the hook-like part, I form integrally with said shank an elongated flange F bordering a correspondingly elongated straight wall G extending lengthwise of the shank. This flange is per forated as at H, and the inner face of the flange is provided with a groove J, for purposes to be now brought out. The bar is provided with an elongated portion K reduced in thickness to accommodate the flange on the shank and provided with a similarlyelongated straight edge L to ex tend alongside of and abut the shoulder or straight edge on the shank to which I have already referred, this elongated reduced portion of the bar being integrally formed as at M with a locking pin N projecting therefrom and through the alined aperture ofthe flange on the shank, a cotter pin or similar device 0 being provided for the protruding end of the pin and enabling the parts to be detached should occasion require.

The inner face of the reduced extension of the bar is provided with a lug P adapted to interfit with the inner grooved face of the flange of the shank, as will be clear, this lug engagement and the straight edge or shoulder engagement between the bolt and the side of the shank offering ample abutment and strength to resist strains exerted upon the bar from within the eye as well as from without the eye in a direction toward the shank.

The opposite end of the closure bar is provided on that edge which faces the interior of the eye with a tongue Q adapted to abut a complementary outside tongue R at the end of the hook-like portion of the eye to additionally reinforce the bar at this point against outward pressures exerted from within the eye.

Normally the closure bar will be removed from the eye when the attaching link or ring may be inserted, and then the bar my be placed in position by a facewise insertion of the same to effect the interfitting of the tongued portions of the bar and hook-like portion of the eye, as well as the interfitting of the lug and complemental grooved portions of the other end of the bar and the flange of the shank. The insertion of the locking pin and engagement of the cotter pin therewithwill effect the relatively ermanent closure desired, reinforced against all normal pressures and strains, as stated.

While I have herein disclosed one specific embodiment of the present improvement, it will be understood by persons skilled in the art that the invention is capable of incorppration in other forms and devices as may withii'rthe scope of the hereto appended claims. For example, as distinguished from the provision of a removable device such as the cotter pin arrangement, the locking pin maybe in thenature of a rivet of a lasting character or capable of destruction to permit-the separation of the parts under emergentconditions; also that as distinguished from the overlapping tongue engagement be tween the end of the bar'and the end of the hook-like member, these terminal portions may be'formed to project one into the other to resist lateral movement of the bar in all directions.

Having thus described the invention, what I claim is:

1. A device of the character described comprising a hook part carried by a shank, and means for closing the s ace between the end of the hook part and t e shank including a separate bridging bar adjoining at its opposite ends the end of the hook part and a portion of the shank, and means connecting the said bar to the shank to prevent relative movement thereof in any direction save by destroying the connection between the bar and the shank.

Coplel of thh patent may be obtained for 2. A device of the character described comprising a hook part carried by a shank, and means for closing the space between the end of the hook part and the shank including a separate bridging bar adjoining at its opposite ends the end of the hook part and a portion of the shank, and means connecting said bar to the shank to prevent relative movement thereof in any direction save by destroying the connection between the bar and the shank, and connecting means comprising anelongated portion overlying a contacting portion on the shank and a pin securing said elongated portion at a point intermediate of its ends to an tion of the shank. 3. 'A device of the character described comprising a hook part carried by a shank, and means for closing the space between the end of the hook part and the'shank including a separate bridging bar adjoining-at its opposite ends the end of the hook part and a 'portion'of the shank, and means connecting the said bar to the shank to prevent relative movement thereof in any direction save by destroying the connection between the bar and the shank, the connecting means comprising a pin uniting adjacent portions of the bar and shank and an interfitting lug and recess engagement between the bar and shank at a point spaced from said pin.

In testimony whereof I hereunto aflix my signature in the resence of two witnesses.
